SwitchplusIP Wins APCO Hot Product Award

New Platform for Radio Voice Crossbanding
Interoperability between all your disparate communications equipment including digital radio, analog radio and vehicle intercom
Simplifying Radio Over IP technology
The Radio Voice Crossbanding System (RVCS) was developed by C4i in conjunction with US Army PEO-I using a mix of COTS and Government GFX Software and Commercial Hardware.
The resultant product provides crystal clear voice communications crossbanding among any Vehicle Intercom (VIC-3/5), Digital Radio Systems (WNW, SRW, EPLRS, EHF/UHF, NCW/WIN-T, etc.), and Analog Radio Systems (SINCGARS, HF/UHF, Bowman, etc.) providing Point-to-Point & Push-To-Talk communications from Brigade to Battalion to Vehicle and down to the Soldier.
The C4i RVCS provides a unified tactical voice communications solution for brigade to battalion & lower. It does this by providing voice Crossbanding capabilities over multiple military tactical and LMR/P25 radios and SATCOM, supporting reach back and combat voice communications over TYPE 1 secure network, including SUITE B-SECURE sharing suite interconnections and radio systems.
The system is TYPE 1 security and IA capable per DoD UCR2008 and NIST FIPS 140-2 compliant with integrated SIP/RTP and AS-SIP/SRTP support.
The RVCS is available in four and eight port options while keeping the same compact footprint.

VOIP/ROIP Terminology
What do they have to do with Radio Over IP systems?
Other questions include what codecs do you support? Do you support MELPe? Speex? But more importantly we need to know why someone might want to use one codec rather than another.
In my next post I'm going to discuss these topics and what they might mean for Radio Over IP solutions for public safety and defense communications.

Upgraded fire control centre launched at Gold Coast Airport
General Manager ARFF Andrew Rushbrook said the fire control project involved the replacement of existing systems with a standardised modern digital system.
"It incorporates the very latest technology integrated communications and incident management resources to give Airservices fire fighters the best tools to manage any incident," Mr Rushbrook said.
It replaces the current patchwork of stand-alone systems with one fully integrated digital system.
By linking airports using IP technology, the new system provides a remote monitoring capability to improve efficiency, safety, and lower training and maintenance costs. The standardised system will also support easier transfer of employees between stations.
More information can be obtained from Airservices Australia.

Connecting the RIU to Cisco Call Manager
I recently visited a client to integrate radio over IP into a system they were developing that provided telephone and video conferencing to a vehicle over satelite. Not knowing the exact configuration of the other equipment involved I brought my RIU for connection to the radios and also a VS-64, (see earlier entry), for push-to-talk access.
As often happens during customer tests and demonstrations plans changed upon my arrival. The customer had configured Cisco Call Manager in his vehicle and this was connected by a satelite link to a remote building which had another Cisco Call Manager installation. They wanted to add the radio as an extension on the telephone system so that they could make calls from phones in the vehicle or in the remote building and talk to a field worker with a portable radio.
I hadn't planned on this, but since the RIU has a SIP user agent I suggested we could possibly set up the radio as a SIP extension. After 10 minutes of configuration changes we had added the RIU to their network and set up a SIP dial peer on the Call Manager installation. We could make calls from the IP phones, and wi-fi phones on the network. I was quite surprised at how simple this was and how good the audio quality was.
We were using military SINCGARS radios and using voice detection within the RIU to generate the PTT signal.
